At present, the world's magnesium resources are very rich, ranking 8th in the earth's crust, accounting for 2.35% of the crustal mass. Magnesium alloy has the characteristics of low density (about 1.78 g/cm3), high specific strength, excellent electromagnetic shielding and vibration and noise reduction, good heat dissipation, excellent biological characteristics and environmental friendliness. It is used in aerospace, transportation, high-end equipment and construction. 3C products, leisure products, energy storage equipment and other fields have a wide range of uses, known as the 21st century green materials and strategic new materials, has been highly concerned by the world, and is expected to become the third foundation after steel and aluminum. Metal structural material.

China is a major magnesium alloy research country in the world. The academic papers on magnesium alloy furnaces published by Chinese scholars have been ranked first in the world for more than ten years. The total number of invention patents applied for and authorized is also far ahead in the world of intellectual property; the world's most plastic magnesium alloy material is developed, the widest Magnesium alloy sheet, the largest magnesium alloy hollow profile and the largest diameter magnesium alloy ring; the invention of a series of industrial lead technology such as self-purification, anti-gravity filtration, new asymmetric processing, high-precision rolling of sheet metal; Elsevier has founded the world's first magnesium alloy journal, the chairman and secretary of the International Organization for Standardization (ISO) "Magnesium and Magnesium Alloys Committee"; many of the world's top magnesium alloy scientists, often come to work with Chinese scientists on magnesium alloy research jobs. Since the first International Conference on Magnesium Alloys was held in Beijing in October 2003, six international conferences on magnesium alloys have been held. Each meeting brought together the top magnesium alloy scientists from dozens of countries including Germany, the United States, the United Kingdom, Canada, South Korea, Japan, Australia, and the scientific and technical personnel of representative magnesium and magnesium alloy enterprises. The latest research results of magnesium alloys and The effects of its large-scale industrial application have been fully demonstrated at each conference.

China is a major producer of magnesium and magnesium alloy deep-processing products in the world. It has a large number of cast magnesium alloys and wrought magnesium alloys. The 2017 magnesium production and export volume account for 3/4 and 2/3 of the world respectively. Ranked first in the world. According to incomplete statistics, there are more than 100 magnesium and magnesium alloy deep processing enterprises in China, and more than 20 important magnesium alloy research and development platforms at the national and provincial levels. More than 50% of the international standards for magnesium and magnesium alloys are drafted and formulated by China. The world's largest magnesium alloy grade, more than two-thirds of the world's automotive magnesium alloy parts are produced in China. For the first time in the world, the production line of wrought magnesium alloy sheet with an annual output of more than 5,000 tons has been realized. For the first time in the world, large-scale production of wrought magnesium alloy and large-scale application in textile machinery, 3C products, rail transit and other fields have been realized. Magnesium alloy furnaces show an increasingly broad application prospect.

China's magnesium mine resources are abundant, and proven reserves rank first in the world. Magnesium alloy has also become one of the few metal materials in China with international voice. With the gradual commissioning of magnesium smelting in Qinghai Salt Lake, China's advantages in the field of magnesium metal will be further strengthened. However, China and the global magnesium alloy industry also have many challenges: First, the market application scale is still very different from the bulk of basic metal materials; second, compared with steel and aluminum alloys, basic research is still quite lagging; third is suitable for High-performance alloy grades for large-scale market applications are still under-represented; Fourth, insufficient attention has been paid to the development of new magnesium smelting technologies. The low-cost advanced deep processing technology of magnesium alloys cannot fully meet the needs of larger-scale production and application; The level of scientificization needs to be further improved, and the construction of magnesium alloy database and product design platform needs to be strengthened. We expect more outstanding scientific and technological workers to join the research and development team of magnesium alloy furnaces to make new contributions to the realization of China's major countries from materials to materials.
